Help chanigng FrameStyles images

[Agathorn]

Yay! I finally got it!

Some things I learned: (Note this is based on doing it in the UIBuilder)

1) Trying to piece together a window frame from multiple image files is much harder than a single one. Unless all the pieces are in the same coords in both files.

2) The SourceRects are important. This is used for alignment internally. NW, N, NE should all have the same top and bottom Y for example. This keeps them lined up.

3) Changes to SourceRects don't always show up properly at first. For example it might not change at all, or it might look squished or stretched ugly. This is ok. If you go to your RectangleStyle and just arrow through the properties it refreshes.
